Even better, don't alias rm; instead, pick a command name like
'delete' and alias that to 'rm -i'.  Why?  Eventually you'll be
working on a system that doesn't have the alias, or you forget to put
the alias in root's dotfiles, and carelessly type 'rm *' expecting to
be asked for each file.  Lacking the alias, you won't be asked, and
will likely be quite upset at the results.
